What would you like? I have gone back a few pages and seen your z bearings do not look secured to the plastic. They are a different style than what I am using. If you look at the picture of mine on the last page you will see I have a bolt that goes through my plastic to hold them bearings tight in place. Those are official Geeetech X carriage parts downloaded and printed from thingiverse. I have them on my home made printer also. But because that frame mounts the z rods too close to the frame I had to mirror the images before slicing and then mount the x carriage backwards so those ends would fit on my frame..
